WILLEEAM FRANK MULLANEY, 0F MARSHALL, MINNESOTA ADDING-GOUNTER Specification of Letters Patent.

Patented Aug. 13,1912.

Application filed May 1, 1911. Serial No. 624,277.

Be it known that I, WILLIAM F. MUL- LANEY, a citizen of the United States, and a resident of Marshall, in the county of I2 on and State of Minnesota, haveinvented a new and Improved Adding-Counter, of which the following is a full, clear, and exact description.

My invention relates to a new and improved adding counterr'and an object of my invention is to provide. a device which will,

accurately measure the travel of a reciproeating element. In the counters now in common use, it is not possible to accurately measure the travel of a reciprocating body,'

such as a piston rod' ofia pump',.dhe to the fact that tie cou'nterdoes not register until the entire stroke has been made.-

A further ob'ect of my invention is to overcome the d ciencies common to. the old form of counters,'.and to arrange 'an- Instrument which will-.measure the travel of the moving body irres .ective vof the len th of the stroke and whic will automatica y add up the travel of the moving body.

I attain the above outlined objects by attaching to .the reciprocatin body, an arm which actuates a gear whee each time the sis - reciprocatin moves in one of its directlons, an wilIcarr, the wheel around a distance. proportionate'to. the 'travel of the reciprocating bodyin that direction. Every complete revolution of the ear wheel will actuate a ineter,- so that as the total number oflrcvolutions' are, recorded and as the circumference of the gear wheels bears a definite ratio to the length of travel of the ,re-

ciprocating member, the number of revolutions times, the circumference of the wh el- 1n the accompanying drawin s, and more particularly pointed t i t e appended claims.

Reference is to be had to the accompany ing drawinga'forming" a part tofithls peclficatio'n; inigwhich similar oharacters of refs erence indicate corresponding parts in all the figures, and 1niwh1ch-- Figure 1 is a side elevation showing a preferred embodiment of my invention;

Fig.- 2 is an endiview of the same lookin from the right-hand side of Fig. 1; an Fig. 3 1s a-transverse sectional view taken 'on the line 33 of Fig. 1 and looking in the direction of the arrow.

Described more in detail, I have shown a reciprocating body in the form of a shaft 4, to which is pivotally connected ajswingthrough said reciprocating member 4 and is adjustably positioned in a slot 7' extendlng lengthwise through the arm 5. The upper end of the arm 5 is pivoted to a supporting shaft 8, which shaft is supported In-any convenient manner by means of a' bracket 9 bearing against which is a jam nut 10, and upon the opposite side of the bracket) from the nut 10 is a collar 11.

Mounted upon the shaft 8 adiacent the collar 11, is a collar 12; mounted upon which last-mentioned collar is a ratchet wheel 13, the teeth of which are engaged by ing arm 5, by means of a bolt,-8 which passes a pawl 14 pivoted at 15 to the arm 5, and

normally; 1n with the ,teeth of the ratchet 13. The ratchet 13and the pawl 14 form a one-way ,pawl-and-r'atchet connection, so that as the reciprocating body moves in the direction spring-pressed engagement indicated by the arrow in Fig. 1, tlze ratchet wheel 13 will be moved anti-clockwise. When the shaft 4 has reached the limit of its movement in the direction of the arrow and begins to retreat, the pawl 14 of course runs' back over the teeth of the ratchet 13. -The ratchet itself is prevented from mov-' ing by'being engaged by the pawl 17 disposed in the same direction as the pawl 14, which. pawl 17 is carried'on a shaft 18 extending at right angles from the-outer end of an arm 19, the inner end of which arm is mounted on the shaft 8. Extending from the shaft' 18 is a bracket 20, which bracket carries oneend of a leaf 5 ring 21, the other end of which is attache to the pawl 17, maintaining said pawl in engagement with the teeth on the ratchet 13. It will be seen that b this arrangement, the ratchet 13 is held rom retarding as the reciprocatingrod moves in the direction contra to the d1- 'rectiop shown b the arrow in Fig. 1.

v Mdiintedoni e shaft 8 is a meter-carrying arm 22, which arm is slotted at 23 to adjustably position the same on the shaft 8. The arm 22is of a'general L-shaped form in cross section, to the small leg 24: of which is attached a meter 25 of any preferred construction. To the shaft 26 of the meter is attached one end of an actuating arm 27, which arm is offset, as shownat 28, to extend a short distance parallel to the outer edge of one side of the ratchet 13. Disposed on the side face of the ratchet-13 is a stud 29 adapted to engage the offset portion of the arm 27. As the ratchet is rotated, it will be seen that at each complete rotation of the ratchet 13, the stud 29 will actuate the arm 27, and thereby cause the meter 25 to register one point. In order to return the arm 27 to its normal position, as shown in dotted lines in Fig. l, a tension spring 30 is. provided, having one end thereof hooked into one of the recesses 31 in the arm27 and having its other end telescoping a guiding stud 32 extending upward from the bracket 20. The lower end of the tension spring 30 is fastened to the bracket 20.

Many changes could be made'in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof. It s intended that all matters contained herein in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is merely intended to cover all the generic and specific features of the and relativities of invention herein described, and all statements of the scope of the invention, which, as a matter oflanguage, might be said to fall therebetween, and that materials, sizes parts are non-essential, except as called for in the claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In an addingD counter to measure the distance traveled y a reciprocating-member, in combination, a shaft, a swinging arm pivoted to said shaft and pivotall connected to the reciprocating mem er, a ratchet freely revoluble on said shaft, a spring-pressed pawl pivoted to said arm, engaging said ratchet to actuate the latter in one direction, a pair of arms mounted on said shaft, one of said arms carrying a meter and the other of said arms carrying 'a spring-pressed pawl adapted to engage the ratchet to hold the same after it has been fed by the pawl on the swinging arm, an arm actuating said meter and extending adjacent to and at one side of said ratchet, a tension spring having one end attached to said meter actuating arm and having'the other end attached to said pawl-carrying arm, and a stud in line with said meteractuating arm.

2. In an adding counter to measure the distance traveled by a reciprocating memher, in combination a reciprocatin member, a shaft, a swinging arm pivote to said shaftand pivotally connected to the reciprocating member, a ratchet freely revoluble on said shaft, a spring-pressed pawl pivoted to said arm, engaging said ratchet to actuate the latter in one direction, a pair of arms mounted on said shaft, one of said arms carrying a meter and the other of said arms carrying a spring-pressed pawl adapted to engage the ratchet to hold the same after it has been fed by the pawl on the swinging arm, an arm actuating said meter and extending adjacent to and atone side of said ratchet, a tension spring having one end attached to said meter-actuating arm and having the other end attached to said pawlcarrying arm, a stud in line with said meteractuating arm, and means locking. said arms in angular relation to each other to vary the-.
